The patient inquires about how his body will kill pathogens unassisted by antibiotics.
The nurse responds that a process called phagocytosis will:

Choice A rationale

Shaking linen when removing it from the bed is incorrect as it can spread microorganisms into the air and contaminate the environment and other surfaces.

Choice B rationale

Turning faucets on and off using a paper towel is correct because it prevents recontaminating the hands after washing, maintaining hand hygiene.

Choice C rationale

Freely taking items in and out of the isolation room is incorrect as it can lead to cross-contamination and spread infections outside the isolation area.

Choice D rationale

Considering items dropped on the floor as usable is incorrect as items on the floor can become contaminated and pose a risk of infection if reused.

Choice A rationale

Organisms that cause the infection refer to the pathogens such as bacteria, viruses, or fungi. In the context of pneumococcal pneumonia, the organism is Streptococcus pneumoniae. The lungs do not serve as the organisms; they are the site of infection.

Choice B rationale

Transmission of the disease involves the spread of pathogens from one individual to another. Pneumococcal pneumonia is transmitted via respiratory droplets, not the lungs serving as the transmission medium.

Choice C rationale

Mode of transfer refers to the mechanisms by which an infection spreads, such as direct contact, airborne, or vector-borne. The lungs are not a mode of transfer; they are the site of infection.

Choice D rationale

Reservoirs are places where pathogens live, grow, and multiply. In the case of pneumococcal pneumonia, the lungs act as a reservoir where the bacteria can grow and cause infection.
